Thanks for the testcase and the timing results. Very interesting. I
would expect a significant slowdown using Cygwin, but didn't expect
this bad.
Here's what I get on Ppro 200, 128MB, NT SP3/FAT, no CYGWIN env var,
all binary mounts:
Cygwin B20:
real 1m39.00s
user 0m29.00s
sys 1m4.00s
Specifying CYGWIN=nontea drops the time a few seconds.
MSVC
real 0m15.00s
user 0m3.00s
sys 0m10.00s
UWIN
real 0m53.00s
user 0m17.00s
sys 0m36.00s
> GNU-Win32 398.3
> Linux (FAT) 6.2
> Linux (Linux FS) 6.1
> U/WIN 41.0
> Win32 14.8
Your Cygwin time is much higher than mine for some reason.
